Is cross stitch collectible?

If Tomb-Sweeping Day's whole set of riverside paintings are available, it will be very valuable. After all, not many people embroider, and it takes a long time to embroider. The quality of embroidery should be consistent, there is no robe line, and the distance between the hook and the belt should not be long. It is best to put it in the vertical needle on the back. When collecting, it is not allowed to be placed in a damp place, and it is best not to put it in a bobbin to avoid moisture.
